T 0 all whom may concern:

Be it known that T, Leon A. FLINKER, a citizen of the United States,residing in the city of Detroit, county of \Vayne, and State Oflt'iichigan, have invented. a certain new and useful Honing andStropping Machine, oi which the following is a specification.

This invention is a machine particularly adapted for sharpening razorblades of all types, and embodies means for both honing and stroppingsuch blades.

This invention is a machine of that type wherein a blade holder when atrest is re tained in a position substantially midway between the leadsof a running strep, whereby a razor or other blade may be inserted into,or withdrawn from, said blade holder in a manner to avoid cutting thestrep or the hands of the operator.

The device or machine embodies means whereby the strep may be presentedat dit ierent inclinations or angles to the sides of the razor blade tobe sharpened, thereby varying the effective action of the strep, andpermitting the blade to be subjected to either a honing or a stroppingaction; means for indicating the relative adjustment of parts when thedevice is used for honing or stropping, respectively, and guidingdevices, such as rollers, provided with suitable flanges whereby theedges of the strep are protected. against wear and abrasion.

An important result secured by one of my improvements consists in a.change .in the angle of presentation of the strop to the side face ofthe blade, according as it is desired to hone the blade or to strep it.In carrying out this part of the invention, I employ certain guides fordirecting the strep, said guides being positioned opposite to the sideof the razor adapted to be carried in. a blade-holder. The guides areadjustable toward or from the blade-holder. When it is desired to honethe blade, the guides are moved outwardly or separated so that the stropwill operate on the sides of the blade and more toward the extreme edgethereof. For stropping the blade, the guides are adjusted inwardly, ortoward the hollow sides of the blade, so as to increase the bevels onthe respective faces of the blade. By a.d justing the rolls, the angleof inclination of the strop relative to the sides oi the blade may bevaried to secure either of the results desired.

For certain purposes, it is preferred to use a specially prepared strep,as when honing the blade.

Other features of the invention, in addilion to those specified, will beapparent from the annexed detailed ClGSCl'lDlilOli and the drawingsaccon'ipanying the same.

In the drawings I have illustrated differentpractical embodiments of theinvention, but the constructions shown are to be understood asillustrative, only, and not as definingthe limits of the invention.

Figure l is a perspective view of a honing and stropping machineconstructed in accordance with one term of my invention. Fig. 2 is aside elevation illustrating the adjustilig and indicatin means wherebythe position of certain strop guides relative to the edge of a blade tobe carried in the blade holder may be adjusted for changing the angleoil the strep relative to said edge of the blade.

Fig. 20 is aview corresponding to Fig. 19 with the locking member free from thestrop actuated member. Fig. 21 is a cross section on the line 1212 ofFig. 20. Fig. 522 is a side view, partly in section, showing anotherembodiment of locking means for the strop actuated member, and Fig. 23is a sectionon the line 1414t of Fig. 22.

The machine shown in Figs. 1 to A, inclusive, of the drawings consistsof a suitable supporting frame, A, a strop, B, and a blade holder, C. Asshown, frame, A, consists of members, A. A pivotally connected togetherby a. shaft, 5, carrying a strop-actuated member, B, employed forimparting movement to blade holder, 0, whereby the respective sides ofthe frame may be opened or spread for the purpose of exposing the bladeholder, so that a razor blade may be easily introduced into said bladeholder or withdrawn therefrom. Member, A, of the frame is shown ashaving locking arm, K, adapted for engagement by a latch, D, whereby thesides, A, A may be locked rigidly with relation to each other. and bladeholder, C, may be held immovably in position with reference to the sidesof the frame, when said frame is opened, as described. In the operativeclosed position of the frame, however, latch, D, is turned to theposition of Figs. 3, 6 and 9, so that the members, A, A may be closedtoward each other, such closed position of the frame being shown moreclearly in Figs. 1, 8, 6 and 9. The form of the frame is not anessential partof this invention, for the reason that I may employ aframe, all the parts of which are rigid or integral with each other. Themachine herein shown embodies a series of six main guides for therunning strop, said guides consisting, preferably, of rollers. Thenumber of guides, however, is not a material part of the invention, forthe reason that I may employ four guides. As shown, two guide rollers,E, E, are mounted for free rotation in the members, A, A respectively,of the supporting frame, said guide rollers being positioned at therespective sides of pivot 6. According to this invention, I prefer toprovide each roller, E, E, with flanges, 6, see Figs. 1 and 2. Saidflanges are positioned near the ends of each roller so as to lie next tothe supporting frame, and these flanges preclude the edges of the strop,B, from rubbing against the frame, whereby wear and abrasion on theedges of the strop are precluded. As shown, the supporting frame carriescertain other guides, F, F, and G, G. The guides, F, G, are preferably,in the form of rollers and they are positioned at the free orunconnected end portions of the frame members, A, A whereas the guides,F, G, are shown as pins attached to the unconnected ends of the framemembers, A, A Obviously, however, guides, F and G, may be in the form ofpins, and guides, F and G, in the form of rollers, but each pair ofguides, F, F, and G, G, should be properly spaced for the leads of thestrop to run between the guides of the respective pairs. H, H, designateother guides which are supported on the respective members, A, Asubstantially opposite to the edge of a blade adapted to be supported inblade holder, C. Guide, H, is shown as a roller which is positionedintermediatethe roller, E, and the guide, F, of member, A. Similarly,the other guide, H, is a roller positioned intermediate roller, E, andguide, G, of member, r The guides, H, H, intermediate the guides, E, F,and E, F, are so positioned that. the strop, B, will be presented at aproper angle to the edge of the blade in holder, C. For honing purposes,the angle of the strop to the face of the blade should be different fromthe angle presented to the blade when stropping it. Accordingly,provision is made for adjusting certain of the rollers to regulate theangle of presentation of the strop to the blade. In the form of machineshown in Figs. 1, 2 and 3, rollers, H, H, are so supported that they maybe adjusted relative to the respective members, A, A of the frame and tothe position of the blade in holder, C. Such adjustment of each roller(H, H) is secured by appropriate devices, one form of which is shown inFig. l. In this connection, it is desired to state that the position ofthe adjusting devices and of the rollers, H or H, is indicated by meanssuch as shown in Fig. 1 and illustrated more clearly in Fig. 2. Eachroller, H or H, is mounted loosely on an arbor, I, each end portion ofwhich is reduced to form a shoulder, i, and a stud, 11. The studs at therespective ends of arbor, I, fit in slots or notches, j, provided inflanges, j, extending at right angles to a plate, forming a part of eachframe memher, A, A Attached rigidly to each arbor, I, are screw threadedstems, K said stems being fixedly secured in any desired way to endportions of the arbor, said stems extending at right angles to thelength of the arbor. Plate, J, of each frame member, A, A is providedwith openings, 70, which receive adjusting nuts, L, L. Each adjustingnut provided with a groove, Z, adapted to receive the edge of anopening, it, in plate, J, whereby the adjusting nut, L, is so connectedto plate J, that the nut is free to turn or rot-ate with respect to theplate, while at the same time, the nut is precluded from becomingseparated or detached from the plate by the edge of opening, is, fittingin the groove, Z, all as clearly shown in Fig. 4t. In the proc ess ofmanufacture nut, L, is of less diame ter at one end. than at the other,and in assembling the nut with reference to the plate, (l, the reducedend is inserted into the open ing of the plate, after which the reducedend is upset in order to form a flange, whereby the nut rotatablyswiveled upon the plate by having an edge of the opening, is, fitting inthe annular groove, Z, of the nut. The nut is provided with a femalethreaded opening, the threads of which engage with the male threads ofstem, K so that the nut, L, will cooperate with stem, K, for the purposeof adjusting arbor, l, and the roller mounted thereon. That part of eachnut, L, L, which projects beyond the exposed face of plate, J, isprovided with angular sides, as shown in Fig. 2, such as a hexagonal nutadapted to receive a wrench for the purpose of conveniently turning thesaid nut relative to the plate. li ith the nut cooperates mcans forindicating the adjusted position of the nut and the roller. As shown, awasher, M, is provided with an opening corresponding to the nut so thatthe washer will fit around the nut in a way to turn therewith. liachwasher is provided with an indicating member, 1a, shown in Fig. 2 as afinger forming an integral part of the washer. The linger extendsoutwardly beyond the edge of the washer, and in one embodiment of theinvention, said finger is represented as having a longitudinal slit, m.The washer and the finger thereon are con nected with the nut so as torotate or turn therewith, and said washer and finger are positioned nextto the plate, J, so that. the washer and the linger will have frictionalcontact with said plate, the frictional contact of the finger with theplate operating to prevent the washer from turning out of the positioninto which it may be adjusted. The plate, J, foii'n'iing a part of eachmember of the supporting frame, is provided with two indicating points,as at o, 0, one of said in-' dicating points being inscribed with thephrase To strep, and the other indicating point having another suitablephrase, such as To hone. Intermediate the indicating points is a stopmember, 0, shown as a pin fixed to plate, d, and disposed in the path offinger, on, said. pin operating to limit the retation' or adjustment ofwasher, M, and the nut, when said nut is turned in one direction or theother. The supporting frame, A, is shown as having a loop 79 to which isconnected an anchoring strap, P the latter being adapted for engagementwith a hook or other fixture, 1 see Fig. 1. Strep, B, is shown as havingsuitable handles, 0, at its respective ends, whereby the operator isable to pull one lead or the other of said strep.

The operation of the machine shown in F 1, 2 and 3, is as follows: l lith the in- (licating fingers, m, adjusted. in contact with stop pins,0, as shown in Fig. 2, rollers, H, H, occupy positions for presentingthe strep, B, at a certain angle to the blade in holder, C, whereby themachine is adapted for stropping the blade. In the machine shown, theframe members A, of are adapted to be opened or spread so as to bringlocking members K into contact with blade holder C, after which latch l)is adjusted for one end thereof to contact with locking member K,whereby the frame members A, A and the holder C are locked in fixed positions, said blade holder C being retained in a stationary positionintermediate the frame members A, r so that the operator is able toreadily insert the blade into the holder. Latch, l), is now u'iovcd awayfrom locking member, K, and the frame members, A, A may then be closedtoward each other, to assume the positions of .l igs. l and 3. Theoperator now pulls on onelead of strep, T, the frictional engagement ofwhich strop with the roller of blade holder, C, causes said blade holderto present the edge of the blade to one load of the strep, substantiallyas shown in Fig. 3, whereupon the moi-'euient of the strop relative tothe edge of the blade operates to sharpen said blade on one facethereof. By pulling upon the other lead of the strep, blade holder, C,is at once moved to present the other face of the blade into engagementwith said other lead of the strep, and the continued movement of saidother lead of the strep operates on the other face of the blade so as tosharpen the same. The operations of pulling first on one load of thestrop, and then on the other lead thereof, are continued so as to strepthe blade to the desired extent, the rollers, H, H, presenting the respective leads of the strep at the proper stropping angle to the edge ofthe blade.

For the purpose of honing the edge of a dulled. blade, it is necessaryto so change the angle of the strop that it will 0])Glt1li0 more to nirdthe edge of the blade, and this is accomplished in the machine shown in1, 2, and 3 by adjusting rollers, ll, ll, outwardly or away from eachother. Such adjustment is effected by applying a wrench to the nuts, L,L, so as to turn the nuts a uarter turn or they ma be turned a halfturn, or a full turn, but shown in Fig. 2, the stop pins, 0, permit thenuts to be turned practically a full turn. l i hen the nuts, L, L areturned a full turn, washers, M, move therewith and the fingers, m, areturned past the indicating point, 0, around to and beyond the indicatingpoint, 0, so as to engage with the other side of the stop pins, thefingers being thus moved from the stropping position to the honingposition. Obviously, the rotation of the nuts will adjust threadedstems, K, and arbors, I, so as to move rollers, H, H, upon the members,A, A of the frame, said rollers being moved outwardly and away from eachother and away from the edge of the blade in holder, 0. The employmentof the fingers, m, on the washers, M, which are adjustable with thenuts, L, L, indicates to the user the position of the rollers, H, H. Nowwhen the rollers, H, H, are adjusted in the manner described, the angleof presentation of the leads of the strop to the faces of the blade isso changed that the strop will operate upon the respective faces of theblade more toward the edge of said blade, and as the rollers are movedoutwardly from the blade and the holder, itfollows that an increasedangle of contact is secured between said blade edge and the strop. Now,when the leads of the strop are pulled first in one direction and thenin the other, said strop acts upon the edge of the blade with anincreased sharpening efiect, and by continuing the operation asufficient length of time, the blades edge will be thoroughly andefiectively honed. After the honing shall have been completed, theoperator may again apply the wrench to the adjusting nuts for thepurpose of restoring the rollers, H, H, to the stropping positions,which positions will be indicated by the engagement of the indicatingfingers, m, with the studs, 0, and the operator may then resume theoperation of stropping the blade until the desired keen edge is secured.

Figs. 5 and 6 of the drawings show a machine similar in many respects tothe structure of Figs. 1 to 4, inclusive, with this eX- ception.lVhereas the guides, F, Gr, of Fig. 3 are mounted in frame members, A, Aso as to be non-adjustable therein, the corresponding guides, F, G, inFigs. 5 and 6 are supported for adjustment relative to the frame as wellas, or in addition to, guides, H, H. As shown, frame members, A, A areprovided with the desired slots, 7', for the arbors, I, of adjustablerollers, H, H, which arbors are provided with stems, K, adapted tocooperate with nuts, L, and indicating members, M. In addition to theseparts, provision is made for adjusting guides, F, G, and for indicatingtheir positions. Accordingly, frame members, A, A are provided withslots, 79, 79, which are parallel to slots, 7', and in said slots arefitted the end portions of arbors, P, P, which carry the rollers, F, G,respectively. As shown in the construction of Fig. 5 arbors, P, P, areprovided with stems Q, which should be threaded, and on which stems arescrewed the adjusting nuts, Q, swiveled or rotatably connected to framemembers, A, A C0- operating with these nuts are the indicating members,R, each having a finger, r, and fixed to the frame members are stoppins, 1", adapted to limit the rotation of the indicating members andthe adjusting nuts. It is evident that rollers, F, G, may be adjusted inthe frame as well as rollers, H, H, and that the positions of saidrollers, F, Gr, are indicated by the fingers of members, R. Provision ismade, furthermore, for the adjustment of rollers, E, E, relative to thestrop-operated member, B, employed for imparting movement to the bladeholder, whereby the frictional engagement of the strop with said member,B, may be regulated as desired. The frame is shown in F 7 and S ashaving slots, 8, s, extending outwardly and radially with respect tosaid member, 13, and in these slots are fitted the end portions ofarbors, E which carry the rollers, E, E, respectively. Said arbors areassociated with adjusting and indicating devices of the kind shown inFig. A, and accordingly, the arbors are provided with stems, S, uponwhich are screwed adjusting nuts, S, rotatably connected to framemembers, A, A Indicating members, T, are connected to the nuts forrotation therewith, each member, T, having a finger, t, adapted toengage with a stop pin, t, see Fig. 7. In lieu of slots, 8, s, extendingradially to the member, B, as just described, the frame may have slots,to, 10, shown in Fig. 9, said slots being parallel to the sides of theframe. It will be understood that. the arbors, E in the construction ofFigs. 7 and 8 may be adjusted inwardly toward, or outwardly from,member, B, for so positioning rollers, E, E relative to member, B, thatthe area of contact between strop, B, and member, B, may be varied; and,further, the adjustment or positions of the rollers will be displayed bythe positions of the indicating devices relative to the stop pins. Asimilar variation in the position of the strop relative to the member,B, is secured by the adjustment of rollers, E, E, in the slots, 21, a,of the structure shown in Fig. 9.

Although I have shown and described rollers, E, E, as having flanges, itwilt be understood that each of the other rollers may be provided withsimilar flanges for precluding contact of the strop with the frame, andthus obviating wear on the edges of the strop.

Figs. 10, 11 and 12 illustrate the means for retaining the blade holder,C, midway between the leads of the running strop, B. This part of theinvention comprises a member, D operated by the movement of the stropfor rocking said blade holder, C, means for retaining the blade holderin a position intermediate the leads of the strep, and means for guidingor directing the leads of the strep. The members, A, A are connectedpivotally to arms, c of a back memher, a whereby the side members, A, Amay be spread or opened relatively to each other, but, when the deviceis in. operation, said side members are closed inwardly toward eachother, as shown in Figs. 11 and 12. Strep operated member, D, ispositioned within frame, A, and it is pivotally supported thereinpreferably on the same pivots which connect the side members with theback member. Said member, D is thus SUPPOltiGCl in the frame for rockingmove ment therein, and this member is operatively connected with theblade holder, whereby the latter will be rocked from side to side as themember, D is rocked by pulling the strep in one direction or the other.Member, D is shown as having a curved or convex face, (I, but on theother side of said member the faces are inclined, as at all, so as toproduce a substantially flattened surface, (Z Blade holder, C, isprovided at its ends with lugs, 0 which are fitted close to the arms, aof the back member, 0?, whereby the blade holder, C, is adapted to bepivotally sup ported within the frame. The means for pivoting the bladeholder shown in Figs. 10 and 12 is embodied in a rod E the same beingparallel to member D and positioned between said member D and the bladeholder. The blade holder is provided with lugs, one of which is shown atc in Fig. 10, but it will be understood that two of such lugs areemployed, said two lugs being positioned near the respective ends of theblade holder. The end portions of rod E pass through these lugs and aresecured in the arms a of the back member, at. The lugs, 0 of the bladeholder are provided at their upper ends with notches, 0, shown moreclearly in the construction of Fig. 18, and in these notches are fittedpins, 0 provided at the end portions of member, I). When the member isturned in one direction by pulling upon one lead of the strep, the pins0 act on the notched lugs, o, for the purposes of swinging the bladeholder in an opposite direction, but by pulling the other lead of thestrep, the member, D is turned in an opposite direction, and pins, 0 act011 the blade holder to reverse its position with relation to the strep,whereby the blade holder is swung from side to side by reciprocating thestrep. l designates a spring positioned rcarwardly of the blade holderand cooperating with member, D and blade holder, C, for the purpose ofretaining the blade holder in a central position intermediate the leadsof the strep. its shown, spring, F is a bowed, curved, or leaf spring,and it is positioned between member, D and blade holder, 0. at itsmiddle portion, spring, I,

is provided with a slot, f, adapted for the reception of a slightlycurved face (Z of memher I), or said member D may have the face (Ztherein flattened instead of curved. Each end portion of leaf spring, Fis provided with a longitudinal. slot which receives the pivotal rod, E.It is apparent that the end portions of the spring are fitted looselyupon the pivotal rod, Whereas the slotted middle part of the springreceives the flattened face, (F, of member, 1). By providing the springwith slots, 7", f, and positioning it for engagement with member, I),and pin, E", the spring is securely retained in position between themember and the blade holder, and, furthermore, said spring iscol'npactly positioned for cooperation with the blade holder, the springlying wholly within the frame and practically concealed by the partscomposing the sharpener, including the strep. The spring, F acts uponbladoholder, C, for the purpose of adjusting said blade holder to acentral position between the leads of the strep. lVhen the member, 1),is turned in one direction by the pull on the strep, one inclined face,d, of said member acts upon the middle part of the spring for thepurpose of compressing it more or less, thus increasing tension thereon.The same action takes place when the member is turned in an oppositedirection, for the reason that the other inclined face, cl, of themember acts on the other edge portion of the spring. When the tension isrelaxed on the strep, spring, F presses against the member, I), andblame holder, C, in such a manner that said member and the blade holderwill be returned to the position shown in Fig. 12, and retained in suchposition so long as the operator does not pull upon strep, B. When aframe having adjustable sides is employed, such as aframe adapted to beopened and closed, I employ arms, K, K, on the side members, A, A forthe purpose of engaging with the blade holder when said members areseparated or spread, whereby said arms, K, K, are adapted for lockingthe blade holder fixedly in position when the frame is opened. As shownin Fig. 11, the arm, K, is provided with a notch, if, and when the framemembers, A, A are closed toward each other, as in Fig. 11, the arms, hi,ii, are moved. away from the blade holder, and the nose of the latch Dengages with said notch, Z22, of the arm, K, thereby locking the sidemembers A, A of the frame n closed positions.

In the construction shown in Figs. 13, l-et and 15, I omit the pivotalrod, E", for connecting the blade holder, C, with the back member, a Onelug, c, of said blade holder is provided. with gear teeth, m and the twolugs, c, of the blade holder are pivoted on the arms, a, of the backmember by short pins or rivets, E. The strep operated member, D, isprovided at one end portion with a gear segment, m and said gear segmentm engages with the gear segment, m of the blade holder, whereby themovement of member, D is communicated directly to said blade holder, C,as shown in Fig. 14. Intermediate its length the member D is providedwith a flattened face, (l adapted for engagement with the slotted middlepart of the spring, F in substantially the same manner as described inthe construction shown in Fig, 12. The end portions of spring, F engagewith the flat rear side of blade holder, (J, and said spring operatesupon the blade holder and the strop actuated member for the purpose ofpositioning the blade holder in a substantially central positionintermediate the leads of the strop. As shown in Fig. 15, the sidemembers, A, A of the frame are provided with inclined shoulders, a atone or both ends for the purpose of engaging with edges of arms, a, ofthe back member, a when said side members, A, A are adjusted to theiropened positions, indicated in dotted lines in said Fig. 15. Theinclined shoulders, (4*, thus serve the purpose of stops when inengagement with the arms of the back member, thus limiting the openingor spreading movement of the frame.

The construction of Figs. 13, 1A and 15 is quite similar to-theconstruction of Figs. 10, 11 and 12, except for the employment of theintermeshing gear segments between blade holder, C, and strop actuatedmember, D, the means for pivotally supporting the blade holder and themeans for retaining spring, F in operative position intermediate themember and the blade holder.

The construction illustrated in Figs. 16, 1'7 and 18 embodies a frameall parts of which are rigid, thus differing materially from the threepart frame of Figs. 10 to 15, inclusive, wherein the pivoted framemembers A, A are adapted to be opened and closed. The frame consists ofa back piece, a and two side pieces, a", a, rigidly connected to eachother, said parts composing the frame being preferably stamped from asingle piece of metal. The sides, a, a, of the frame are cut away, asshown in Figs. 17 and 18, to produce slots or openings, n, and betweensaid side portions is positioned the blade holder, C, and strop actuatedmember, D The blade holder is shown as having the lug 0 provided with anotch c, and in said notch is fitted a pin 0 whereby the member I) isadapted to impart movement to the blade holder. The blade holder ispivotally supported within the frame by rod, E, which is positionedintermediate the blade holder and the member. Spring, F is positioned,also, between the blade holder and member, D so that it will act toretain said blade holder in a substantially central positionintermediate the strop when no tension is applied to said strop. Saidsprin F is slotted as in the construction of Figs. 10 to 12, inclusive,and it is retained in operative position by the means and in the mannerheretofore described. Instead of employing six rollers, as in theconstructions heretofore described, I construct the frame, A, so that itwill support four rollers, or equivalent guide pins, for strop, B. Guidepins, 0 0 are positioned in the rear part of the frame, A, and at therespective sides of the member, D said guide pins being provided withrollers, 0 0 respectively. The end portions, a, (1 of the frame areprovided with inwardly extending lugs, a in which are mounted adjustingscrews, p engaging with guide pins, 7), the latter supporting guiderollers, P P respectively. The rollers, P P are positioned nearlyopposite to the end portion of blade holder, C, for the purpose ofdeflecting the strop inwardly toward the sides of a blade adapted to bepositioned within a blade holder. The strop is looped within the frame,its bight is spread by rollers, 0 O and the respective leads of thestrop are inclined by rollers. P, P inwardly toward the blade holder,whereby the strop is adapted to be presented atproper angles to therespective sides of a blade in holder, C. The device is adapted to besupported in any suitable way, and as shown herein, the back member, aof the frame is provided with lugs, a", supporting a pin, 5 to which isconnected a hanger B The stropping machine shown in Figs. 19, 20 and 21of the drawings embodies the ge neric features of the invention asheretofore described. The frame is, preferably, of the same type as theframe, A, in Figs. 16, 17 and 18, said frame supporting four guide pins,O O and P P similar to the rollers, 0*, O and P P of Fig. 17. Bladeholder, C, is provided with lugs, 0 which are attached rigidly to stropoperated member, D so that the blade will swing with the strop operatedmember. In the constructions heretofore described, the strop passes fromone rear guide to the other and over a convex face of the strop operatedmember, but in the construction of Figs. 19, 20 and 21, the strop passesbeneath the strop actuated member so as to engage with the under convexface thereof. The guide pins or rods, 0 0 are supported directly in theend members of the frame, but the other guide pins, P P are attached tostems whereby they may be adjusted substantially by the means previouslydisclosed. Instead of employing a spring positioned intermediate theblade holder and a strop actuated member, heretofore described, I employa spring, F which is positioned rearwardly of member, D The stropactuated mem ber, D is shown as having a flattened or curved face, 6 andwith this curved face engages a retaining stem, Q1 which is actuated byspring, F Said retaining stem is provided with a head, Q, positioned forengagement with the flattened 01' curved face, d, of the strep actuatedmember 1). Spring, F is provided with a slot for stem, Q to pass throughit, and said spring is positioned for its ends to engage the backmember, a, of the frame, the middle part of said spring, F acting uponthe head, 9, of stem, (Q The back member, (15, of the frame is shown ashaving lugs, a, adapted to support a. pivotal pin, 6 to which is pivoteda hanger, B The hanger is shown as a plate having a tapering slot, 6 andsaid hanger is provided with a. lug, 2'), to which is pivoted the outerbent end of stem, Q, as shown. The hanger is adapted to be turned to aposition parallel to the back plate, a, of frame, whereupon spring, F,presses stem, Q in an inward direction so that the head, 1, of the stemwill engage the flattened face, d, of member, D, whereby the stem, Qacts to retain member, D and blade holder, C, in position, said bladeholder being retained in a position substantially midway between therespective leads of strop, l3. Vihen it is desired to use the device,the operator pulls on the strop and adjusts the hanger D to a positionsubstantially at right angles to the frame, as shown in Figs. 20 andThis operation causes lugs, 32*, of the hanger to pull on stem, Q,against the tension of spring, F and the stem, Q, is pulled fromengagement with member, D, the spring being cmnpressed, as shown in.Fig. 20, and the member, D, being released from the action of the stem,whereby the strop, B, may be operated for imparting motion to member, Dwhich member swings the blade holder alternately in one direction andthen in another direction.

The same general results and mode of operation described in connectionwith the construction of Figs. 1? 20 and 21 are adapted to be secured byanother construction illustrated in Figs. 22 and 23 of the drawings. Tla strapping device shown in the two fig ures last mentioned embodies thesame general features as the device of ,liigs. 19 and E21, inclusive,except that the means for retaining member, D and blade holder, C, aremodified in the following particulars: Theflattencd face, o', of member,l), is adapted to be engaged by the inner part, 7 (l ig. of yoke shapedretaining device, R. The legs, W, of this retaining device are fittedslidably in openings, r provided in the back plate of frame A. Throughthe yoke, 15/, passes spring, F the ends of which bear upon the backplate of the frame, while the middle part of said spring acts againstthe cross piece, T of the yoke with the shaped retaining and pressuredevice. The

a, of the lugs, whereby yoke, It is adapted to be moved relative to thestrop actuated member, D, by the pull of hanger, B on the pin, 7)", andupon the legs, 1*, of said yoke. The yoke is pressed into engagementflatten-ed face of member, 1), by the spring, 1 but the yoke may bemoved rearwardly in order to .release the member when tension is appliedto strep, B. The

hanger of Figs. 22 and 23 has the tapering slot, 1), described in thehanger of the const ruction shown in Figs. 18, 19 and 20. The

tapering slot is advantageous when used in connection with a hook orother fixture be cause the edges of the slot are adapted to bind uponthe hook or other fixture and limit the sway of the stropping machinewith relation to said hook. In the drawings blade holder, C, is shown ashaving a s -ring, 8 adapted to be adjusted into frictional engagementwith the back of a. razor blade by the operation of a screw, 3, saidspring and screw being positioned and 0p eratcd as disclosed in my priorPatent No.

, enters.

It is evident that the novel features of my new machme may be used inconpmction with different kinds of stropping devices, and that variouschanges in the form, size, proportions and minor details of constructionmay be made without departing from the spirit of the invention asdefined by the annexed claims.

The adjusting rollers previously described are also used to regulate thedistance between the two sharpening faces of the strop on either side ofthe blade holder, C, whereby an even pressure will be applied along theedge of the razor blade. This is accomplished by turning the adjustingnuts in the direction indicated. until the desired PI'GSSUTO between therazor blade and the sharpening faces of the strop is attained.
